Now the game has started crashing for me too, approximately every third WZ match or so. No issues when grinding regular MP though.
The worst part is that it’s not at the beginning but usually after the 2nd or 3rd phase (or even later), which makes it extremely annoying.
Edit: Also, whoever at IW who added Warzone challenges to the ribbons this season can go fuck himself. Trying to get 15 revives from the kiosk when you can only play with randoms is near impossible (since they tend to leave the game when they’re dead).
